Multi-power switch switching method and device

Abstract

The invention discloses a multi-power witch switching method and a multi-power switch switching device. In the method, by acquiring locomotive accelerator pedal position information and / or locomotive load factor information, when the locomotive accelerator pedal position information is greater than the upper limit preset value of an accelerator pedal or the locomotive load factor information is greater than the upper limit preset value of a locomotive load factor, a multi-power switch is automatically switched to the maximum torque value and outputs the maximum torque value; and when the locomotive accelerator pedal position information is not greater than the upper limit preset value of the accelerator pedal or the locomotive load factor information is not greater than the upper limit preset value of the locomotive load factor, the multi-power switch outputs the torque value corresponding to the rotation speed of a locomotive according to a power limitation curve corresponding to the position of a selector switch handle, thus, when the selector switch of the locomotive runs in an underloading or medium loading state, and the locomotive needs more power output, the multi-power switch is automatically switched to the overloading position according to the judgment of the accelerator pedal position information and / or locomotive load factor information to ensure that the locomotive runs in the overloading state, so that the multi-power switch of the locomotive can be switched timely and the dynamic property and the economic operation property of the whole locomotive can be guaranteed. Meanwhile, the switching operation of a driver is reduced.

Description

technical field [0001] The present application relates to the technical field of multi-power switches, in particular to a method and device for automatic switching of multi-power switches. Background technique [0002] At present, the electronically controlled diesel engine realizes multi-power switching through multi-channel resistance converters and switches, and cooperates with the logic limit curve inside the ECU (Electronic Control Unit, electronic control unit). However, the driver needs to manually control the handle to realize multi-power switching. There is the problem of driver's operation delay like this, so that the power and economy of the whole vehicle cannot be guaranteed, and the driver needs to switch frequently and the operation is troublesome. Contents of the invention [0003] In order to solve the above technical problems, the embodiment of the present application provides a multi-power switch switching method to realize automatic switching of multi-po...

[0002] At present, the electronically controlled diesel engine realizes multi-power switching through multi-channel resistance converters and switches, and cooperates with the logic limit curve inside the ECU (Electronic Control Unit, electronic control unit). However, the driver needs to manually control the handle to realize multi-power switching. In this way, there is a problem of delay in the driver's operation, which makes the power and economy of the vehicle unable to be guaranteed, and requires the driver to switch frequently and make the operation troublesome.
